How to use this tool
- Open the page you want to check, view its page source, and copy the HTML.
- Paste it in — the checklist updates automatically.
- Fix anything marked Missing or Issue, using the detail line for context.
Common mistakes to avoid
- Don't paste a page's rendered DOM (from DevTools' Elements panel) instead of its source — that can include changes JavaScript made, which isn't what search engines see on first crawl.
Why check meta tags in the browser?
This uses the browser's own DOMParser to read the HTML you paste — nothing is sent to a server, so it works equally well for a public page, a staging site, or a page still behind authentication.
Frequently asked questions
- Why do I paste HTML instead of entering a URL?
- A tool running in your browser can't fetch another website's HTML directly — browsers block that (CORS) for security. Pasting the source you already have (View Source, or Ctrl/Cmd+U on the page) means this works for any page, including ones behind a login, with no server involved at all.
- How do I get a page's HTML source?
- Open the page, right-click and choose "View Page Source" (or press Ctrl+U / Cmd+Option+U), select all, and copy. This shows the HTML as delivered, before any JavaScript changes it — which is closer to what search engines and social platforms actually see.
- What does "meta description longer than ~160" mean?
- Google typically truncates search result snippets around 155-160 characters — a longer description usually just gets cut off, so it's a mild warning, not an error.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online meta tag checkers |
|---|---|---|
| Works on staging/private pages | Yes — paste-based, no fetch needed | Usually no — most require a public URL |
| Data ever leaves your device | No — 100% client-side | Often yes — the URL is fetched server-side |
("Typical online tools" reflects publicly documented behavior of common free file-processing sites as of 2026 — always check a specific competitor's own privacy policy and pricing page, since these details change.)
